Application filed January This invention relates to improvements in molds andv jambs for windows and similar closures for wall openings.

An object of this invention is to provide a window jamb with an adjustable staff mold which permits the construction of variously sized windows, and which will permit the mounting of these windows in a wall opening which may not have the exactsize corresponding to the window dimensions. In other words, in constructing a building an opening may be leftin the wall which is of a size somewhat larger than the window which is to be used. A window is selected which will be receivable within the opening, and by means of the improved jamb and adjustable staii' mold the window can'be caused tofit the opening. The improved construction is quite important in that in constructing brick walls with wall openings it is unnecessary to cut any brick. The brickmay be laid in any bond and any desired joint, and when the wall has been completed, by ascertaining the dimensions the wall opening the window of the nearest size which will lit within the wall openingis selected and the adjustable jamb and staff mold will cause it to fit, although the width of the wall opening may vary.

lVith the foregoing and other objects in view which will be made manifest in the following detailed description and specifically pointed outin the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of they invention, wherein: V

wherein similar-reference characters designate s1m1lar parts throughout, the wall is generally designated at having .an opensecuring part 16 and to the side of the wall opening. It is also provided with a portion 20 arranged parallel to but spaced from the securingpart 16 and with a portion 21 which extends towards the side of the Wall opening. The particular form or arrange ment of the two portions 20 and 21'is immaterial, and, if desired, this may be changed to present an ornamental appearance. The essential characteristics ofthese two portions is that they combine to form a part extending from the. forward edge of the portion 19 rearwardly and outwardly toward the sideof the wall opening 11. The edge of the portion 21 is preferably reversibly bent upon itself, as indicated at 22, for purposes of. stiffening.

' An angular member has a portion 23 positioned against thesecuring part 16. This portion is rigidly secured to the securing partas by spot welding, riveting, or the equivalent. The angular member also has a portion 24 which is arranged at right an gles to the portion 23 and adjacent the portion 19 of the staff mold. The forward edge of the portion 24 preferably reversibly bentupon itself, as indicated at 25, for purposes of stiffening. The side 15 of the jamb is disposed between the portions 19 and 24 times be found desirable formed therein.

' the wall opening 11.

the jam]. applied, the side wall is caused to slide between the portions 19 and 241, thus permitting the adjustment of the jamb relatively to the staff mold or Vit'O versa.

In this form of construction, which is shown in Fig. 2, the jamh and stall mold have been primarily "designed for use upon brick-and concrete walls. Inmounting the staff mold upon such walls, it may some to take a brick saw or equivalent insetrument and out a groove in the side of the wall opening 11 for the reception of the reversely bent portion 22'of the portion 21 of the staff mold, thus presenting a neat and finished appearance. This construction, however, is optional.

The advantages and utility of the improved construction are as follows: In constructing the wall 10 the wall opening 11 is In forming this wall opening, the bricklayer or mason does not out any brick, but merely lays out time brick in any desired bond. and any desired joint so that the width and height of the opening are the next oversize as permitted by the hrick'over the desired window dimensions. The windows are constructed of various widths which vary at about half brick lengths. Their heights can be varied by thicknesses of bricks. After determining the dimensions of the Wall opening 11, which has been left bythe mason or bricklayer, that window is selected which is the next size smaller than the dimensions of The staff molds are secured in place and the jambs 12 are applied. These jambs are then adjusted so that they will lit the window selected. After the jamb has been adjusted, the inside finish plaster P can be-applied, and that portion of the plaster which extends upon the side of the wall opening 11 is caused to join the edge of the'side wall 14; of the jamb 12, thus holding the jamb in its adjusted position. After the jambs have been set, the window guides of any desired construction can be secured tothe front wall 13, and any cross braces which may be used in a plural sash windowcan also be applied. At the same time, the head and sill can be positioned over the top of the staff mold and jainb and beneath the staff mold and jamb respeclively.

Because of the fact that the improved jamb'and adjustable staff mold provide an adjustment, it will be readily appreciated that it is only necessary to construct and keep in stock a set of windows varying in width by half brick lengths and in height by brick thicknesses, and that'thes'e windows can be used regardless of the particu lar sizes of wall openings formed by the various masons. The. adjustment between the staff mold and the jamb is preferably not less than one-fourth of a brick length,

so that when two jambs with their adjustable staif molds are used, the dimension between the front walls 13 of the two jambs can be varied at least one-half of a brick length and thus :u-commodate any window.

Th'eahove mentioned construction is primarily designed to be used upon brick and concrete walls.

In the modification shown in Fig. 5, the jamb and adjustable staff mold have been primarily designed to be used upon stucco or plaster walls. These walls consist of studs S, against the inner side of which there is ada 'jted to be positioned plaster P, and against the outer sides of which there may be applied stucco or plaster ()1 In this modification, the jamb has a front wall and the side walls 1 1-. and 15, and the stati mold has the securing part 16 and the portions 19, 20 and 21. The edge of the portion 21, however, instead of being reversely bent upon itself, is provided. with a hooked flange 26, constituting a ground or guide for the outside plaster O, and behind which the plaster may be positioned to lock the edge of the staff mold in place. The adjustment of the jamb 12 between the portions 19 and 24; is the same as in the modification shown in Fig. 2. This jamb and adjustable stail' mold areused in the same manner as before, it being merely necessary to select the window which is theinext size smallerthan the window opening, position the staff molds and jambs in place and thus cause the window to fit the opening. In this modifica tion, however, the side wall 141. isp'refer'ably' caused to assume a position flush with the surface of the plaster P, as determined by the plaster ground 27. As the thickness of the outside plaster 0 may vary m'som'e 1n= stances, it may be necessary 'to"espec ally construct the staff mold so that the distance between the flange26 and the side wall; 14 will be equal to the thicknessof the wall;

From the above'described construction it will be readily appreciated that'the improved jamb and adjustable staff mold will eliminate the cutting of brick in forming brick wall openings. Furthermore, it will permit various windows to be kept in stock and the windows selected which will fit the various openings. As the staff moldand jamb are formed of metal, they form tireproof window casing, and also a casing which is very rigidly held in place, and which will be strong and durable'. v

It will be understood that various changes in the detail oflconstruction may bemade without departing from the spirit or scope of the invention as defined by the appended claims. f x V .I;claim: 1.
